I don't believe it's the Registry's job to provide history.  Historical 
background information may be useful in some cases to help users make 
good language tagging choices, but not for its own sake.  It would be 
hard to tell where to stop; there would be no point in adding a comment 
to the region subtag 'US' to point out that the United States were once 
colonies of Great Britain.

There is no provision in the drafts for any comments to be mandatory, 
and in my opinion there should not be.

Since Comments fields are free-form text, it would hard to see how 
applications would use them, other than displaying them.

I have to modify draft-4645bis (which I'm sure is what you meant) again
